Looking for a 500W-600W around £40

[bradderzd1994]

I've been trying to look for a decent PSU for the past few days, it's all i need now to power my new system. However i am having troubles and not sure what to get. I understand a lot of these cheap ones are not very reliable and can blow up in a matter of weeks. However i'd like a decent PSU obviously not top of the range but at a decent price and a reliable name.

Price range would be prefered £30-£40 however if it's a good bang for the buck i don't mind paying a little more.

If anyone could help it would be great.

It is going to be powering

Intel i5-650 3.2Ghz
4GB DDR3 RAM
500GB HDD
Radeon 6870

Resolution will be 1920-1080

If there's any other specs you would need to know please tell me thanks

Anything 40+ on this list would probably be OK

nothing standout, but nothing poor either.

Coolermaster or the XFX, XFX because of the ampage (44A), but it only has 1pci-e(6) and 1 pci-e(8), the GTX680 needs 2 x 8 for instance but you have plenty of power for it. The coolermaster has 2x8 but doesn't show the amps. (the web appears to say 44A, but coolermaster doesn't declare it, which I don't like)

The best bang for the buck is the XFX Pro 550W that 13th referenced: http://www.scan.co.uk/products/550w-psu-xfx-pro-series-core-edition-p1-550s-ukb9-85-eff-80-plus-bronze-sli-crossfire-eps-12v-fan-at

How about the lack of upgradability, i.e. being able to fit a single high end card? Does the single rail mean that a molex to pci-ex8 adaptor would work well.

You're right in that the XFX has one 6-pin and one 8-pin PCIe power connector, therefore won't support a single high-end GPU like the GTX580, HD 6990, or the GTX 690, without a molex to PCIe 8-pin PCIe adapter plug like this: http://www.ebay.com/itm/Molex-IDE-PCI-E-8-pin-VGA-Card-Power-Cable-Adapter-/290497779139

The PSU that does have two 8-pins and is in the approximate price range and I would recommend is the Enermax Pro82+ 525W: http://www.scan.co.uk/products/525w-enermax-pro82plus-epr525awt-triple-pci-e-rail-atx12v-23-88-eff-airguard-safeguard#ProductFeatures
Scan specifications state that the OCZ ZS 550W has two 8-pins and it is in the price range, but OCZs specs on the PSU state that it has one 6-pin and one 8-pin (I would go with the mfr): http://www.ocztechnology.com/ocz-zs-series-550w-750w-power-supply.html If there is a european version that has two 8-pins, then I didn't find it listed on their website.

Going with one of those PSUs means that the OP would have 3yr warranty vice a 5yr warranty. The OP did not mention an upgrade to SLI/CF or an upgrade to a card that requires two 8-pin PCIe power connectors. I would go still go with the XFX and use a molex to 8-pin adapter if I needed two 8-pin PCIe adapters. The XFX with 44A on the 12V rail while the Enermax has 40A and the OCZ has 38A, so I think the XFX would have a better chance of handling the single higher end card.

Edit: What route would you take?
