Silent power supply recommendation

I need a 300ish watt atx power supply to replace my noisy one, in my experience the "silent" ones are often far from it...

Can anyone recommend a nice and quiet one at a reasonable price. Thanks

There's no such thing as a silent PSU at a reasonable price. That's unless one's fortunate enough to pick up a secondhand bargain on eBay or similar. E.g. £90 for totally silent, fanless 300-500W ones at click here & click here.

Scan are doing a few 'Super silent' Silverstone PSUs on their Todayonly page click here, starting at £50 that could be amongst the quietest non-fanless PSUs. The 350W Be Quiet one at eBuyer for £30 click here might be reasonably quiet too. Also consider this £40 400W Corsair click here. All the above make quality PSUs & one can't really go wrong with them for the money.

If you want zero noise, you'll need to stump up the cash for one, or be patient for a bargain in the auctions. G

My Corsair 520w is almost silent, cost me about £65. By way of comparison, a PC World £35 brown box 450w one made by Jeantech was about 100 times louder and I thought that was quiet at the time compared to a 350w cheapie that expired and forced me to get the Jeantech.

Regarding wattage, am I right in thinking the psu only uses what it needs, so using a 500w to replace a 300w for example will not use any more electricity...

That's right thewasp, but if the difference is great, efficiency might suffer.

E.g. a 300W PSU for 250W actual use might have a 85% efficiency. But a 500W PSU for the same actual usage (250W) might only be 75% efficient.

Sbrads, I also have the same PSU, & can confirm that it's relatively silent. G

I see ebuyer are doing a 400 watt Corsair for around £40.

What other brands are well regarded?

Though it only uses 300 watt if its 500 watt it will not have as much work to do so it should last longer and you will not notice the difference in cost to run as it only uses what it needs not what its got

"I see ebuyer are doing a 400 watt Corsair for around £40."

See my initial post.

"What other brands are well regarded?"

Apart from Silverstone, Be Quiet & Corsair - Antec, Enermax, Tagan, Seasonic, Etasis, OCZ (or PC Power & Cooling), Zalman, Coolermaster, Xigmatek, Hiper, FSP, Akasa, Thermaltake, Gigabyte. G
