More PSU help needed

A short while ago I asked for help with noise that was diagnosed as likely to be from the PSU. The noise is becoming very persistent and annoying and I am looking for a reasonable replacement PSU.

My current PSU is a Hiper Type-R Series 480W unit which I have searched for online but been unable to find. As a result I am looking for a reasonably priced replacement and become quite confused.

I searched Amazon for PSUs and found a very large number. I also read up on them and found the experts consider the cheaper units can be suspect in their specified outputs and heating - this has been borne out by some reviews I have read.

I have searched quite a few sites and found a number of PSUs that may do the job that are in my price range (e.g. Coolmaster) and one or two that are at the very top (e.g. Corsair) but I am still uncertain if any would suit my purpose as I am aware that AMD CPUs and graphics cards in SLI have specific needs.

I am open to suggestions other than those examined, but would like a quiet, half decent item that will last as I can always keep it as a spare and may use this PC for storage (or similar) when I replace it.

Could I yet again throw myself at the mercy of those who have the technical ability to advise as to a suitable and reliable unit, please.

With thanks in anticipation.

Indeed it would look like the model you have, as now been discontinued. It looks like the nearest recommended substitute is the Corsair.

Ebuyer had these advertised, so I would suggest that you email them, and ask what they have as recommended replacements?.

Many thanks for coming back again.

I was considering a budget of around £40 but would be willing to go to around £55 if the PSU was worth it.

I posted links to a couple of PSUs that may do the job in my original request. Whether these are any good I don't know for certain but they looked hopeful to me.

Given the existing PSU is 480W (nominal) and I have added two extra HDDs, I think I need to be around the 500W mark; although, within reason, the larger the PSU the less strain it will see.

The system: Motherboard Asus A8N-SLI Deluxe 3 x HDDs all SATA 2 x CD/DVD drives ATA (Molex?) 1 x Floppy drive - which I use Case fans (Molex) 2 x Asus 6600GT PCI-E (I think these are powered through their motherboard slots)

Does this give you enough information?

Thanks for coming back spuds.

At least I appear to be right about my existing PSU not being available now; it also looks as if Hiper are in the same boat.

I have posted for gengiscant as he requested and shall await his suggestion/recommendation as well. It looks as if I shall need to look towards the top of my budget, but if the PSU is good and can be used elsewhere in an emergency then it is worth it.

Many thanks for the information.

It seems I was headed in the right direction as your first link (Coolermaster) is the same item as mine and the Corsair unit is the same range but lower output; hence cheaper. The Antec unit is not one I found.

Although more expensive I am drawn to the Corsair unit. My preferred supplier would be Overclock as I have used them before. However comparing the specification and part numbers there appears to be a slight difference; could it be the Scan Specification is slightly older than the one shown by Overclock? I also like the fact I can save a few pounds as well!!

Many thanks to you both.

I had no intention of going for a cheap PSU for the very reason you mention gengiscant, but I have never built my own PC (a project I am considering next year as a replacement for this PC) and have some difficulty understanding the compatibility of components - hence this question.

I only need 3 SATA connectors in this PC and have a splitter for the molex already. If anything I am likely to have a number of ends to tie off.

Thanks again.

You may be interested.

I found this Corsair 500W unit which I thought was good value along with its partner the Corsair 600W PSU.

"Hmm,the 600W usually delivered in 1-2 months .."

Amazon regularly make this statement on items. I actually ordered the 600W unit with my expectation it would come much earlier; e-mail today confirming dispatch as 5 December, delivery 7 December.

Given the higher price charged by Scan (£54.72) and Overclock (£52.74) plus their delivery of around £5 for either, it's looking a good deal at £49.99 delivered, don't you think? The odd day shouldn't make that much difference, unless the existing PSU goes down which given that I've put up with it for a few weeks already is hopefully unlikely.

I can put the odd few quid towards something when I get my replacement PC - when allowed!!

I think I have just found another problem

The PSU has a 4+4 (or 8 pin) EPS plug according to the specifications given on the sites looked at. The motherboard has a 4 pin (square layout) CPU power supply socket and an EZ socket (Molex?) for the graphics cards when used in SLI as I have them. The original PSU has a 4 pin CPU power supply plug and Molex connectors.

I have searched for an adapter cable which would provide a step down from the new PSU (due tomorrow) to a 4 pin power supply + (ideally) a Molex plug but have been unable to find a suitable item. The best I have found is this; will it do the job and/or is there a better item, perhaps with a Molex plug on the lead as well, that you know of?

  johndrew 13:28 04 Dec 2011

I have found that the 8 pin plug on all Corsair PSUs is clipped together and easily splits to provide 2 x 4 pin plugs - no problem, just me.

The new PSU is fitted and very quiet; even my wife remarked on how much quieter the PC now is!!

For any with an Asus motherboard that has an EZ plug for graphics cards in SLI, as I have, there is likely to be a need for a Molex extension cable to reach. My old PSU had 8 Molex plugs on two cable looms, this one has 4 on a single loom. As a result there is a shortage (for me) of Molex plugs easily fixed by use of splitters and extensions. Another point is there are more than ample 6+2 connectors and SATA power connectors most of which need tying back.

Once again, my thanks to all who offered help.
