Replacement PSU Recommendation Please

[GM2]

Hi

I built the below system about 4 years ago, with one exception, I used a Corsair HX520W PSU that I already had, which I've just checked and actually dates back to 2008!

The system has been generally great for what I wanted and needed. But recently it's started to randomly immediately shut down, especially if the sun is shining on the case as it does late afternoon. Takes a knock on the side of the case to get it to fire up again. Suggestion from Electrical Engineer son is that it's most probably a dry solder joint in the PSU.

Given the PSU is now 15 years, probably due a change. I'm happy to consider either a direct replacement or to upgrade it for something better and with a bit of future proofing.

Recommendations for a replacement please?

My basket at Overclockers UK:

• 1 x MSI B450M Mortar MAX (Socket AM4) DDR4 mATX Motherboard= £92.99
• 1 x AMD Ryzen 5 3600 Six Core 4.2GHz (Socket AM4) Processor - Retail= £179.99
• 1 x Zotac GeForce GTX 1660 SUPER Twin Fan 6144MB GDDR5 PCI-Express Graphics Card= £218.99
• 1 x Crucial Ballistix Sport LT BLS8G4D32AESBK 3200 MHz, DDR4, DRAM= £79.99
• 1 x Sabrent 1TB Rocket NVMe PCIe M.2 2280 Internal SSD= £109.99
• 1 x WD 3TB Blue 5400rpm 64MB Cache Internal Hard Drive (WD30EZRZ)= £84.95
• 1 x Corsair CX-M Series 550W 80 Plus Bronze Semi Modular Power Supply (CP-9020102-UK)= £73.99
• 1 x Kolink Citadel Micro-ATX Case - Black= £39.95

Thanks for the quick responses. A bit more info...

PC is used 75% for web browsing and general 'office' uses. I work from home about 3 days per week, when it is on from say, 08:00 until probably 22:00 or later.

The rest is a mixture of:
Various photography related stuff, including some Photoshop etc.
Some gaming. Would need to check what games, but mostly Call of Duty, some GTA and a bunch of other Steam and random games.
A bit of video editing, but not masses.
Some design programs (1x grad engineer, 1 at uni).
Bits of VR.
etc etc etc.

Price - no fixed idea. Happy to spend whatever is sensible. Maybe £130? But more if necessary. Less if no need to spend more!

Hope that gives enough info?

...However, to support any further CPUS or GPU in a future build, you can consider a ATX3.0 spec like the MSI MAG A750GL 750W 80 Plus Gold ATX 3.0 PCIE5 £100. Both of these are overkill for the current system but can be taken through to your next build.

Thanks for this suggestion.

At that sort of price, it seems well worth paying the extra for ATX3.0 and more power.

Are you recommending this specific model because it's a good choice in it's class? Or mainly because it's in stock at OCUK?

For £130, I'd get MSI's A850G PCIE5, but it is not in stock right now. That'd be sufficient for anything up to a 4080.

Thanks for the suggestion. Compared to the MSI MAG A750GL 750W, is it mainly just another 100W for £30 or is there more to it than that?

Looking at MSI website, MPG seems to be a tier up from MAG?

 

[GM2]

I've seen the MPG 750 for about £100 too.

Toying between the MPG 750 or 850 (£100/£130). Both overkill for now, but both with a chunk of headroom for a future build.

Anything else at that size/price etc I should consider. If not, very happy with these suggestions.

Thanks all for your help.

Is that not the pre-ATX 3.0/PCI5 A750GF? I don't think I've ever seen the A750G PCIE5 for sale in the UK.

Ah!! You may well be correct!

Will be going with this:

My basket at OcUK:

• 1 x MSI MPG A850G PCIE5 UK PSU 850W 80 Plus Gold Modular Power Supply (SKU: CA-00Y-MS) = £130.00

Total: £130.00 (includes delivery: £0.00)​

Many thanks everyone for your guidance and suggestions.
