Our PSU is 150 x 81.5x 40.5mm, which is 15 x 8.15 x 4.05cm so according to this info, it should fit. You can check with the case company, and give out our PSU dimensions to make sure, just to be safe. **Q: Will this fit in a hp m01-f0134 replacing a 180w power supply?** A: From what I can tell of that model, I would say yes. At least by physical dimensions. One thing of which to be mindful is that this PSU has a 24-pin connection to the motherboard. So, you should verify what type of connection your motherboard supports - I had to buy an adapter because my MB had a 14-pin connector. **Q: Does this unit's fan push air to the unit or exhaust it out?** A: Pushes air into the unit **Q: Looking to swap 40mm fan with Noctua but they only make 10mm and 20mm deep fans in this size. Do I go with the 10mm and then... tape around the gaps?** A: Get the Delta AFB0412HB. It is 40mmx15mm and quieter than stock fan. Not as quiet as Noctua, but def quieter and meets spec for this PSU ## Customer Reviews ### ⭐⭐⭐⭐⭐ Asesome Flex PSU for the price *by K***Y on June 22, 2023* My build included 13th Gen i7 with onboard graphics (no standalone graphics card), Rog Strix B760-I, FSP mini ITX 500Watt Flex Power Supply (PS) along with Noctua NH-L9i (37mm low profile), M.2 NVMe and 2 RAM sticks, all fitted in the really compact Goodisory A09 Black Mini-ITX 0.8mm SPCC Desktop Computer Case.After fitting everything in, the PS wire harnesses seemed to be using a lot of room and blocking the ventilation holes. I had to cut a lot of unused pieces of the wire harness to make room for ventilation. I could have gone with the 300 Watt modular version perhaps.However, once I had cut off and sealed the ends of the excess wire harness pieces, it was great. The temps in my case are very low and this PS contributes little to the heating or to the noise. There is a 40mm fan that runs pretty quietly. In a perfectly quiet room where this PC is always on, I hardly hear the PS fan noise. The processor fan noise from the Noctua, which itself is very low, is the only noise I hear from the build.Very good value for money IMO and a great Power Supply overall. ### ⭐⭐⭐⭐⭐ Great psu for compact itx case. *by R***N on September 7, 2021* The psu run great and the noise only during starting up the pc.If it modular with the same size it will be much better.I only able to reach around 360 watt stress test for 11500+3060ti xc and still run silent though I have noctua and scythe fan as a backup to replace the fan if it noisy.Since it run silent during gaming which only consume up to 240watt on average, I just use the stock fan without replacing it. ### ⭐⭐⭐⭐ Does what it's supposed to *by A***N on December 3, 2020* It is fairly quiet until you play a game. Then it gets quite a bit louder, but if noise isn't an issue for you then go for this PSU. It feels really quality and I haven't personally had any issues with it. I might swap the fan that it came with for a different one, like a noctua; but so far I don't care for the noise since I wear a headset a majority of the time anyways. There isn't much choice when you want a psu this powerful at this size, from what I have gathered, it is slim pickings. Overall, I'm pretty happy with it, it fit inside the GEEEK A31 V2 with plenty of room to spare. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/210034252-flexguru-pro-500w](https://www.desertcart.at/products/210034252-flexguru-pro-500w) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-05-04*
