Need a new PSU?

My PSU needed replacing this week, after 2 and a bit years, and I did some sums.
Budget PSU £35 / 30 months, 30% energy wasted as heat
Quality PSU £50 / 60 months, 5 year warranty And 15% Power saving, 80+ bronze certified.
If you can afford it there are even more efficient power supplies with longer warranties 7 or 10 years.

Not to mention that a quality PSU is less likely to fry your expensive hardware...0

The only thing to beware of is that when premium quality PSUs fail, you might have to pay postage overseas to get them repaired. I've been told by a retailer that he stopped selling Antec PSUs as they have to be returned, either at his or the customer's expense depending on how old it is, to the Netherlands. I heard some time ago that Corsair's have to be sent to the USA.
Having said that, go for quality evertime. My Antec Truepower New 550W is worth every penny compared to the cheap ones I generally used before. Quietness, construction, solid Japanese capacitors, efficiency, far less heat being emitted, peace of mind that my components won't get fried the way that my sister's Tiny PC did...0 -
If you want a great PSU that will last you a lifetime, you need to get yourself a Corsair (80Plus Gold)... They might cost a little bit more, but honestly it's worth every single penny. The fan doesn't even spin on mines it's that power efficient (and I have a powerful graphics card, i7, cathodes led's etc running from it)!
Warranty wise, they offer you 7years - if that doesn't tell you they are serious about how reliable they are, nothing will... Mines has been powering away every single day for over a year now, and hasn't given me a single problem.
If you want a better deal, buy a refurbished one because the 7year warranty will still be in place, and 99% of the time it's just one's that have had the box opened/sent back and can't be sold as new again!
Hope this helps (if any!).0 -
Worth an extra £15 for the [STRIKE]better[/STRIKE] cables!
Nicer sleeving, a cable is a cable after all.
Ample connectors, the right ones too, saves buying adaptors.0 -
Don't get a PSU that provides more power than you will use. Keep it close to your maximum power usage and then it will work at it's most efficient level.
Unless you have a high end graphics card getting 500+ watt PSU's is usually a waste of time, money and energy IMO.0 -
I need the Amps, a lower powered PSU £15 quality equivalent £35.0

a psu only draws what it need ,eg a system need 300w you have a 500w ,its only draws 300w not 500w from the plugA.Penny.Saved wrote: »Don't get a PSU that provides more power than you will use. Keep it close to your maximum power usage and then it will work at it's most efficient level.

That's fine... till you add a few extra hard drives, upgrade the graphics card, want to move the PSU to a different machine, etc. I'd say it would be better to allow for a decent bit of "headroom" to allow for future system changes...
And I doubt that a 500W-rated supply providing a mean 200W would be significantly more efficient than a 650W-rated one... would it?!0 -

Not wishing to be rude, I can't agree with that advice. Ask any electrician, he/she will tell you that capacitors do degrade over time and become less efficient, so by have some headroom means the PSU has to work less hard, and will maintain its efficiency for longer. Secondly as Esuhl says. extra items, USB devices, etc do get added/changed over time, so another reason to not to be too mean with the PSU size.0 -

To use your words, "Not wishing to be rude" but you are simply showing your total ignorance on this matter by posting that rubbish!
The advice posted by A.Penny.Saved above is spot on. Bigger is not better if the extra capacity is not required or used.:doh: Blue text on this forum usually signifies hyperlinks, so click on them!..:wall:0
