PSU Buying.

[xTH3xMoDsZx]

Hi!

 

I'm looking to buy a PSU for my new PC components, as my current one, periodically is making an electrical hissing/ticking noise, only when under load and sounds like it's not going to last any longer.

 

PC Specs:

 

AMD FX 8320 @ 3.50GHz

 

ASUS M5A99FX PRO R2.0

 

Corsair 4x2GB 1600mhz

 

(Old) ASUS AMD HD 6670 1GB

 

(Old) EVO Labs 700w PSU

 

NOTE:

• I'm under a budget of £45 ($70.) As I've already blown £255 ($396) on these components.

 

I've tried the Cooler Master PSU calculator and kinda get confused when it asks about "Physical CPUs," 1-4, as this CPU (AMD FX 8320) is a 4 Cores with 8 Logical processors, I wasn't too sure.

 

 

If anyone could help, that would be most appercatied!

 

Many thanks,

Alex

 

P.S:

Going to attach the PSU noise I was on about.

PSU Noise

Not sure if your recording equipment is properly picking up what you're hearing but the noise can be a result of coil whine.

The PSU Calculator is referring to physical cpus and not cores--there are motherboards with multiple sockets. I'd avoid psu calculators since they tend to be unreliable. Stick to power draw benchmarks instead.

The 8320 has 8 physical cores.

 

If you're looking for a new psu, a decent 300w would already be plenty: http://uk.pcpartpicker.com/part/evga-power-supply-100b10500kr

Cheers, buddy! Thanks for the advice - most appercatied.

 

Wouldn't Corsair be a better choice when it comes to PSU's? (So I've heard)

Corsair like many other brands doesn't manufacture their own psu's but instead rebrands from OEMs. There are a variety of Corsair psu's both better and worse than the 500B.

The reason why you see Corsair recommended as a brand and not their individual units is probably due to people who just repeat parts of what they read.

You need to quote a post or tag a member or else they won't get a notification you replied to them.

Corsair was the one who started the whole psu fetish a long time ago. They have a generally good rep with a few hiccups along the way. They "make" decent psu's but have a tendency to get overpriced. OTOH, they also have great sales. Their tiers are denoted by the letter codes on the names. CX is the basic psu. Ok. Nothing special. CS is a little step up. They sell a ton of these psu's and they are always on sale. A 430W unit will do you just fine. The RM line is decent but overpriced. EVGA is killing them at the 750W stage and up because they are offering a better unit for less. The HXi series is another step up, just slightly better components. Their AX and AXi units are the top of the line. Premium products for premium pricing.

 

There's other companies that do just a good of a job or better, a lot of the time cheaper as well. EVGA is doing very well at the moment with their G2 and P1 lines particularly cleaning up. Seasonic is a manufacturer and they are a damn good source. The Corsair AX line is made by them. Shop around and see.

 

For your budget I would go with either semi or fully modular. You shouldn't need more than 650W for anything. If you can, look for units that have a silent mode which allows the fan to remain off until a certain temp is reached. Make sure the fan is a ball bearing fan. At your price point you have a bunch of good choices. Don't accept anything less than Bronze certified. Have fun!
