The i7 9700k/RTX 2070 super was functioning yesterday. After restarting, a white screen appeared. I rebooted again, but fans and lights activated without a display or working USB. Reseating the GPU and CMOS battery didn’t help. Booting without the GPU worked. Once the GPU was reinstalled, the issue returned. I noticed my system only shows 8GB RAM even though I have two 8GB sticks. I attempted to reseat the RAM, but the PC still loops during boot. I’m unsure if there are multiple problems. I plan to test the GPU and RAM on a friend’s machine and check the PSU with a multimeter. I’m not sure if the motherboard or CPU is the cause, but I hope this helps before replacing parts piece by piece.
Full system specifications, including the PSU make and model (or part number), are not available. The age of the PSU cannot be determined, and it is unclear whether the PSU was new or used/refurbished. It seems unlikely that the PSU caused damage to the motherboard or failed on its own. Possible causes include a CPU issue, though the PSU typically takes priority in failures. The RAM problem appears unrelated, as the issue with the PCI-E x16 slot persisted even after changes. Booting with an iGPU suggests the main problem lies elsewhere.
This Apevia Prestige 800W doorstop? Details here: https://www.apevia.com/products-power-supply/atx-pr800w To be honest? 😱 If it’s genuine, this PSU stands out as the top choice (and perhaps the only one). Most Apevia models are of questionable build. While some may be mediocre, anything from Apevia should never be purchased. A fresh PSU is essential, particularly since this unit came with a three-year warranty and has long since expired. Likely the issue arose when the PSU malfunctioned, emitting voltages outside acceptable limits that harmed your motherboard, which then caused further damage. Now, running your system on this faulty power supply risks total failure of your entire setup. I’d recommend inspecting all components in your second PC to ensure they function properly. Because a failing PSU can easily cause widespread damage, acting as a catalyst for disaster. Some may argue you bought it pre-assembled and couldn’t replace the PSU, but hidden risks exist with pre-built systems—often low-quality units are included to attract customers who lack technical knowledge. For new units, consider these reputable options: Seasonic Focus/Vertex/PRIME, Corsair RMx/RMi/HXi/AXi, Super Flower Leadex Gold/Platinum/Titanium in the 650W range (if your RTX 2070 Super is still operational). If not, and your GPU is also affected by the Apevia unit, a 650W model works for RTX 4070 Super. GPUs like RTX 4070 Ti or Ti Super require a 750W unit. For further advice on your Apevia model, check the PSU tier list here: https://forums. You’ll find it in Tier C, low priority units—indicating poor quality. This is essentially junk compared to the high-end options. Even for average builds (Tier B), it’s barely sufficient for a non-gaming PC without a dedicated GPU. Personally, I use Seasonic PRIME TX-650 and PX-550 models in full specs with photos attached. Additionally, consider the longevity of your PSU: - 2 years: very unreliable - 3 years: still unreliable (e.g., Corsair VS/CS) - 5 years: moderate reliability (e.g., Be Quiet! Straight Power 11, Seasonic G12, Corsair CX/CXF) - 7 years: decent reliability (e.g., Seasonic Core/Focus GM, Corsair TX/AX) - 10 years: reliable (e.g., Seasonic Focus GX/PX, Corsair RMx/HX/HXi/AXi) - 12 years: excellent reliability (e.g., Seasonic Vertex/PRIME) In summary, aim for a PSU with at least a decade of warranty. Remember, your Apevia unit currently has only three years of coverage.
Thanks for the extra details. I had no idea much about computers, but the prebuilt one I got has performed well enough for five years. It seems like upgrading the PSU, motherboard, and possibly the CPU would be wise since it's a 9th generation model and needs compatible parts. I’m hoping my GPU and other components won’t fail and will last longer before I upgrade further. Thanks for your help!

Note: With latest Intel CPUs (12th gen, 13th gen and 14th gen), you have option with MoBos, to either use DDR4 or DDR5 RAM. For time being, i put in MoBo that supports DDR4 RAM, so you can re-use yours. But if you go with AMD Ryzen 7000-series or 8000-series CPU then DDR5 RAM is a must.
As with everything, you can go higher or you can go lower.
E.g CPU: i5-14600K is solid mid-tier. Lower (cheaper) option on Intel side would be i5-14500 or i3-14100. Higher (more expensive) option would be i7-4700K or i9-14900K.
CPU cooler is value king. You will not find better air cooler with less cost. So, no point to replace this one. Just make sure your PC case can support 155mm tall CPU cooler. If not, you need to go with smaller air cooler.
MoBo: Z-series is high end, but also offers more features. You can go cheaper if you like, e.g: H770 chipset or B760 chipset. Or you can go higher, especially when picking a MoBo that requires DDR5 RAM.
And PSU is between good and great quality. Vertex is ATX 3.0/PCI-E 5.0 compatible and has 12 years of warranty. But you can go lower, e.g Seasonic Focus (good quality, 10 years of warranty) or higher, e.g Seasonic PRIME ATX 3.0 (great quality, 12 years of warranty). But with PSUs, don't go below good quality/ 10 years of warranty.
